[Russell] Martin, a Canadian citizen, told Greg Hamilton, the Baseball Canada head coach and director of the national teams, that he wants to play shortstop in the W.B.C. Hamilton was receptive to the idea.

Canada has two major league catchers on its current roster, including Martin and Oakland’s George Kottaras, who is from Scarborough, Ontario. But it does not have a major league shortstop.

Martin played shortstop in high school and college, and has logged 75 1/3 career major league innings at third base. It might not be the prettiest thing to watch, but the 29-year-old can probably pull it off.

“If it’s something that would help the team, I am willing to do it,” Martin told the Times on Saturday in a telephone interview from Montreal, Quebec. “I told Greg I want to do it, and he said he’s open to it.”

Martin is still an MLB free agent but has drawn interest recently from several teams. The Mariners, Rangers and Red Sox have been linked to him, and the Yankees should be ready to make some sort of offer soon.

The Cardinals have officially signed outfielder Dexter Fowler to a five-year, $82.5 million contract. Fowler will also get a full no-trade clause.

The Cardinals gave Fowler a bigger deal than many speculated he’d get, as some reports predicted he’d get something in the $52-72 million range. His skills, however — he’s a fantastic leadoff hitter who plays a premium defensive position — definitely earned him some major dough. Fowler hit .276/.393/.447 with 13 homers, 48 RBI and 13 steals over 125 games in 2016 for the World Series champion Cubs.

For the Cardinals, this will allow Matt Carpenter to move down to the middle of the batting order and will shift Randal Grichuk to left field. It also takes a prime piece from the Cardinals’ biggest rival. For their part, earlier this offseason the Cubs signed former Cardinal center fielder Jon Jay. So that’s fun.

The Cardinals have always emphasized building from within. In the 2016-17 offseason, however, they may end up being one of the bigger free agent buyers. At least according to some informed speculation.

The Cardinals are already losing their first round pick due to the Fowler signing, so any other top free agent won’t cost them more than the money he’s owed. And as far as money goes, the Cardinals have a great deal of it, despite being a small market team. They have a billion dollar TV deal coming online and Matt Holliday and Jaime Garcia are off the payroll now. Spending big on a free agent or three would not cripple them or anything.

Encarnacion or Trumbo would be first baseman, which wold fly in the face of the Cards’ move of Matt Carpenter to first base (and, at least as far as Encarnacion goes, would fly in the face of good defense). Getting either of them would push Carpenter back to second, displacing Kolten Wong, or over to third, displacing Jhonny Peralta. If you’re going to do that, I’d say that Turner would make more sense, but what do I know?

Either way, the Cardinals may be entering a pretty interesting phase of their offseason now. And an unfamiliar one as, quite possibly, the top free agent buyer on the market.
